JOHN H. PHILLIPS, OF NEYV YORK, N. Y.

BOILER-FEEDER.

I l# SPECIFICATION forming part of Letters Patent No. 289,704, dated December 4, 1883.

Application filed May 17, 1883.' (No model.) l

with a' vessel for receiving water, which vessel is provided with a float adapted to throw a weighted lever for adjusting theslide-valve of the steam-cylinder of the pump, whereby the pump will be started as soon as the water in the vessel rises to a certain level.

The invention also consists in variousY parts and details and combinations of the same, as will be fully described and` set forth hereinafter.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corv responding parts in all the figures.

Figure 'I is a side view of my improved steam-trap, parts being broken away and others shown in section. Fig. 2 is a plan view of the same. Fig. 3 is a longitudinal sectional elevation of the steam-chest and slide-valve in the same.

A vessel, A, of any desired shape, is provided with pipe B, for conducting the condensation water into the vessel, and with ank outlet-pipe, C, for conducting off the water of condensation, which outlet-pipe C is connected with the cylinder D of a pump, and has check-valves E E at each side of the connection with the pump-cylinder D.

The pump-piston F is fastened to the lower To the upper end of the piston-rod G, pro=- The invention consists in a pump connected the pump-piston F, and the arm N. As the jecting over the top of the cylinder H, an arm, N, is fastened, which `proj ects downward at the side of the cylinder H,'aud is provided 55 with two tappets, O 0, separated a suitable' Ashaft, P, is journaled in standardsP on 6o Vthe top of the vessel, and the shaft is provided with an Aupwardly-projecting arm, Q, and a downwardly-projecting curved arm, Q, a

f weight, R, being fastened on the upper end of thearm Q. The shaft is also provided with anarm, S, projecting toward the steam-chest, and with an arm, S', projecting in the oppovsite direction, which arm S is provided in its free end with an anti-friction roller, s. A float, T, contained in the vessel A, is provided with an upwardly-projecting rod, U, passing f loosely through a neck, Y, in the cover of the vessel A, which rod is provided on its upper end with a head, W. The rod U is so arranged that its head can strike the end of the armS. Steam is admitted into the steamchest J by a pipe coupled to the same at Y.

. The operation is as follows: If the parts are in the position shownfthe steam acts on the top of the piston in the cylinder H, and holds the pump-piston F down. Y. When the level of the water rises sufficiently, the iioat T rises, and the head W of the rod U strikes against the end of the arm S, thereby swinging the upper end of the arm Q in the direction of the arrow ct. When the upper end of the said arm passes the vertical line, the weight R throws it downward in the direction of the. arrow a', and the end of the arm strikes the upper end of the rod L, and drives the same downward, thereby moving the valve K downward, and thus admitting steam to the lower end of the cylinder. The steam raises the piston inthe cylinder H, the piston-rod G,

arm N rises, its bottom tappet, O, strikes the arm S, and throws the arm Q in the inverse direction of the arrow d, whereby the end of the bottom arm, Q', strikes the lower end of the bottom rod, L', `and drives the valve K roo upward, thereby admitting steam into the top of the cylinder H, whereby the pump-piston F is forced downward. The upper tappet, O,

against which the arm S strikes, prevents the arm Q from swinging too far in the inverse direction of 'the arrow a. As the pump-piston rises it draws the water through the pipe C into the pump-cylinder, and when the pumppiston descends it forces the water into the boiler. The level of the water in the vessel A has thus been lowered, and as soon asthe level of the water rises again sufficiently to cause the head IV on the rod U to strike the arm S/ the above-described operation is repeated. The device operates automatically in all respects.

The water conducted into the vessel A need not necessarily be condensation-water, but can be derived from any other suitable source.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. Aboiler-feeder constructed substantially as herein shown and described, and consisting` of a pump connected with a vessel for receiving water, which vessel is provided with a iioat adapted to throw a weighted lever for adjusting the valve of the steam-cylinder of the pump in such a manner that the pump will operate as set forth.

2. In a boiler-feeder, the combination, with a steam-pump and avessel adapted to receive water, of a iioat in the said vessel, a slidevalve for governing the entrance of steam to the steam-cylinder of the pump, rods projecting from the top and bottom of the valve, a iioat in the vessel, a weighted rocking lever adapted to be thrown by a rod on the float and adapted to adj ust the slide-valve by striking the ends of the rods of the same, substantially as herein shown and described, and for the purpose set forth.

3. In a boiler-feeder, the combination, with a steam-pump and avessel for receiving water, of a fioat in the vessel, a slide-valve connected with the steam-cylinder of the pump, rods projecting from the top and bottom of the valve, a weighted rocking lever adapted to be thrown by a rod oir the float, and adapted to move the slide-valve, and an arm secured to the top of the pump-piston rod, and provided with tappets for throwing the weighted lever back into position, substantially as herein shown and described, and for the purpose set forth. j

4. In aboiler-feeder, the combination, with the vessel A and its float T, of the steampump D F Gr II, the steam-chest J, the slidevalve K, the rods L L', the shaft I?, having arms Q Q S S, the arm N, having` tappets O Of, the weight R, and the rod U on the float T, substantially as herein shown and described, and for the purpose set forth.
